MQ7 Carbon Monoxide Sensor (20-2000ppm Detection, Analog Output)

The MQ7 Carbon Monoxide Sensor provides reliable 20-2000ppm CO detection with analog resistance output, simplifying integration into Arduino and Raspberry Pi projects. Ideal for air quality monitors, industrial safety systems, and smart home automation.

Wide Detection Range for Versatile Use

Accurately measures CO concentrations from 20 to 2000ppm, suitable for indoor air quality and industrial leak detection.

Analog Output for Easy Integration

Simple voltage divider circuit connects directly to ADC pins on microcontrollers like Arduino UNO or ESP32.

Low Power & Stable Performance

5V heater coil ensures consistent sensitivity, while minimal power draw (≈150mA) suits battery-powered devices.

No Calibration Required

Pre-calibrated for plug-and-play operation, reducing setup time for DIY projects and prototyping.
